AR-15 / M16 9MM Magazine Adapter Block
Posted by andrew on 6th Mar 2015
I installed this in a PSA lower - it fit good. seems to work quite well. Unlike the promag magazine, it is well worth the money - which is FAR less than any other magwell block that I've seen.
promag may have a life preserver with this one !! they finally got this one right .
Would recomend this to anyone building a 9mm AR.

I was skeptical about this based on price compared to the others. It was an excellent fit and with ASC 32 round mags they functioned fine with the stock magazine catch. No modifications were necessary. A little attention to detail is required as you insert the block into the lower to be sure it doesn't hang on the plastic above the mag catch cutout. Also, there is a small plastic bump on the same side of the block and firm pressure will allow the block to be fully seated without shaving off any plastic. I would buy it again.

I made a 9mm for home protection and this is just what the doctor ordered it was no problem to install and works great

Promag has gotten a reputation for making crap products, however this is not one of them. People will tell you that you should get the more expensive magblocks instead of this one, but that isn't true. I am very happy with this product without a single problem. Would definitely buy over and over again

The part fit well for my build and was everything I expected it to be. I most impressed with how fast it got here. Great turnaround on shipping.
